Ponies around the farm?

I have a 13'2 hh pony that I have trained to drag stuff.  He has a well-fitting harness and full neck collar.  He's actually a great riding pony, too, but we're getting ready to move out to some acreage in the PNW and I'm trying to think about what he could do around the farm, you know so he can earn his keep.  My problem is that most people who use equines for farm work seem to use big draft horses, although there also seems to be a small but significant minority using minis and Shetlands.  My pony is neither of those.  He is medium-sized, stocky and built like a tank -- he has the body of a very small draft horse.  What could I realistically ask him to do?  Pull logs, I guess.  Would he be big enough to haul a manure spreader, assuming I could find a manure spreader designed to be pulled by a smaller equine?  Speaking of which, where do I find equipment that is pony-sized?

I think you'd be amazed at what a horse that size can do, especially one like yours that is stocky built.  Here are a couple of links for new equipment that show equipment for all sizes of horses.  You can get ideas on what is out there and available.  I'm sure you can find used equipment online and possibly at the major draft horse sales.  They usually have a day set aside to just sell equipment.  I think you can probably find equipment sized just right for him.
